Detailed Description

template<typename Value, typename Data, typename Function>
class IBTK::CartGridPointwiseFunction< Value, Data, Function >

Data must be CellData, NodeData, SideData, FaceData, or EdgeData of doubles. Value must be double, VectorNd, VectorXd, or MatrixNd: a double callback is evaluated for every depth, VectorNd requires depth NDIM, VectorXd uses the complete depth vector, and MatrixNd requires a TensorStorage and the corresponding depth.

Function must support exactly one of these signatures:

Value(const VectorNd& x, double time, int depth, int axis);
Value(const Value& q, const VectorNd& x, double time, int depth, int axis);

The first initializes data; the second transforms initialized data in place. depth is the scalar depth index, or zero for vector and tensor callbacks. axis is the orientation for side-, face-, and edge-centered data, or invalid_index for cell- and node-centered data.

Ghost values are neither read nor modified, and values shared between patches are evaluated on each patch that holds them.
